Again, you are polarizing.

E von Hoegh, there HAS to be some 'waste' in order to support the negative. What I say is there did not have to be AS MUCH waste.

Consider: if the exposed frame was 30mm X 36mm because of smaller sprocket holes and only on one side of the film, would the image suffer? No. You would STILL have the support needed. And that image would certainly have been better than the standard 24mm x 36mm one we have now. - David Lyga
